I’ll add, that as with so many things, the militanized hyper sensitivity (condemnation of looking) coincided with the aggressive promotion of breasts by women, that we didn’t see before.
What sickens me is women that “show their cleavage” all the time. Not because they do so. But because by the time they turn 40 the area from their neck to thier mid chest has had so much sun damage it looks like george harrison’s plumbers crack. It is not flaunting what you got. But knowing when to flaunt and not to over flaunt.... I hardly ever show cleavage but when I do it is a special and appreciated thing.
